Earth Ponies, as the toys which most resembled real horses came to be known, were soon accompanied by additional species. Pegasus Ponies had molded wings, while Unicorns had horns which purportedly gave them magic powers. Sea Ponies resembled real-life seahorses, apart from the colourful mane they shared with the original Little Ponies. Flutter Ponies were much smaller and thinner than Pegasus Ponies and had translucent wings more like those of an insect, and featured a "fluttering" action. Wing Ponies were even smaller in size compared to the Flutter Ponies, but were proportioned more akin to their larger kin, and had larger distinctly butterfly-like wings. Finally, Mermaid Ponies resembled the mythological hippocamp. Baby Ponies were also available in many forms; they resembled their mothers, but were smaller and typically had softened colors and simplified identifying symbols.

Many different sets of Little Ponies with striking variations were produced, starting with the Rainbow Ponies (which all sported rainbow-colored manes and tails) in 1983. Other notable variations included the So-Soft Ponies (which were entirely covered in fleece), Twinkled-Eyed Ponies (with a small jewel in place of the eyes), Twice As Fancy Ponies (with symbols covering most of the body), and Brush 'n' Grow Ponies (which had a longer-than-usual tail stored inside the body that could be drawn out through brushing).

The line ran for ten years, ending in the US in 1992. Oddly, this year was touted as the celebration year of My Little Pony.
Apart from the ponies themselves, merchandise included children's bedding and room decorations, plush toys, puzzles, and books. There were also more unusual items, such as pomanders and toy sewing machines.
